Internet Explorer 10 - Enable 32-bit or 64-bit IE10 in Windows 7

@Brink,

There seems to be a typo in step 5:
A) Check the Enable Enhanced Protected Mode box. (see screenshot below step 5)

Maybe it should read:
A) Check the Enable Enhanced Protected Mode box. (see screenshot in step 4)

Great info...who knew and the thing about UAC that's scary-
how many other things are affected by -
UAC turned off or down,but really what a mess.
I am not an IE hater ,but what a sordid mess.
And 11 is even worse,God help us all.

Nice to find tutorials to solve problems with Gmail and Yahoo groups message editor using Windows 7, 64-bit and IE10. After trying out IE11 it was not to my liking, so IE10 was put back and that changed some of my settings. To cure the problems I went to:

Tools>Internet options>Security then checked “Enable Protected Mode” in both Internet and Trust sites. That forces IE10 to run in 64-bit mode.

Thanks to tutorials herein things are made easier. :)

Hi.

I want to ask how to run 32bit IE on a 64bit machine running Windows Server 2012 Standard (IE 10)..

I try to play on "Enabled Protected Mode", however regardless of its state (check or unchecked), IE will always run as 64 bit (via TaskManager), each following tab is also on 64bit.

The method of running iexplorer.exe in dir C:\Program Files(x86) also has been tried but to no avail.

According to this read, it will always run as 64 bit.

For IE10, we’ve changed IE such that Manager Processes always run as 64bit processes when running on a 64bit processor running a 64bit version of Windows. This improves security among other things. We do not expect that this change will meaningfully impact compatibility, because the Manager Process is designed not to run 3rd party content, and thus there’s little opportunity for anyone to take a dependency upon the Frame Process’ bitness. In support of this change, the various registry points that point to Internet Explorer have been updated to point to C:\Program Files\Internet Explorer\iexplore.exe. If you manually invoke C:\Program Files (x86)\Internet Explorer\iexplore.exe, that 32bit process will simply launch the 64bit version of iexplore.exe (with the appropriate command line parameters) before exiting.

First of all this topic has helped me loads in figuring out some issues on my desktop. Thank You. I have a Windows 7 Desktop, and had IE 9. I noticed I had the 64 bit operating system but I also had 2 different IE icons in the start program, one for 32 bit/one for 64 bit. I had noticed that when I tried to stream music from certain radio stations, some would stream fine in 32 bit, others only occasionally in 32 bit. I couldn't figure it out until I made a connection with the IE Icons and tried streaming in 64 bit. The other stations streamed without problems. That is, until I upgraded to IE10. My problems began all over again. I seemed to have lost all but one IE Icon. Plus I could not stream again on some radio stations. The problem broke with this article on "Enhanced Protected Mode". It's a little hard for me to comprehend what happened but, when I applied EPM, I could stream music from those other radio stations. I was wondering if the Icons can be replaced ? Can I have an Icon for both 32 and 64 bit again ? 32 bit is (x86) correct ? Or do I even need 2 IE Icons on the desktop ?

Dear Shawn, According information on the Microsoft webpage Change security and privacy settings in Internet Explorer - Windows Help the default setting for 32 bit IE 10 in W7 is to have Enhanced Protected Mode enabled, not "turned off" as you suggest in step 6 of the tutorial. Thanks by the way for the terrific work you do on these forums! Cheers, Adrien
